Enables @babel/plugin-transform-react-pure-annotations. I'm trying to run very simple code, but I'm getting an error, I didn't use the create react app! Installation npm install --save-dev @babel/plugin-syntax-jsx Usage With a configuration file (Recommended) But JSX should come as part of the React installation, so I tried re-running the webpacker react generator: $ bin/rails webpacker:install:react From the logs, I could see this added babel (amongst other things) to the package.json . I started newly writing unit test cases using Jest and Enzyme for the react application and when try to run test cases using jest like "test": "jest --watch" rather "test": "react-scripts test" tests going through babel for the runner to understand react syntax. Using this plugin directly only enables Babel to parse this syntax.
